The channel, aptly named Never Ending Callus, is an ode to — you guessed it
— removing calluses. Pretty gnarly in theory (and on paper), but
trust me when I say these videos are kind of addicting. Kind
of.

The videos' owner — let's call him Never Ending Callus
— says he uploads videos featuring his callus removals (done
with a razor blade!) because he's "always had crazy calluses, and
people seem to find entertainment out of me cutting them off."
Sure, makes sense.

The reason behind his "crazy calluses," though, as Never
Ending Callus tells commenters, is that he has pachyonychia
congenita, a genetic condition that primarily affects the nails
and skin, according to the U.S. National Library of Medicine. It causes the
fingernails and toenails to become thick and abnormally shape,
and blisters and/or calluses to develop on the feet and, although
rare, on the palms of the hands. So, in an effort to get rid of
the at-times painful calluses, Never Ending Callus often takes
matters into his own hands using a trusty razor blade and, at
times, a foot grater to scrape off hunks of dead, yellowed skin.
It's serious(ly entertaining) stuff.

Obviously, I'm not recommending anyone with similar
blisters and/or calluses follow suit — because if you happen to
experience skin-thickening like the stuff seen in the videos,
your best bet in treatment is to skip the DIY sesh completely and
make an appointment with a medical professional. Luckily, there's
no harm in watching the clips — that is — if you can stomach
them.
